fig. 2 is a schematic bottom view of the present utility model.

In the figure: 1. the device comprises a shell 1-1, a bottom plate 2, a driving motor 3, a bearing disc 4, a gear ring 5, a pinion 6, a follow-up limiting ring 6-1, a limiting contact 6-2, a limiting protrusion 7, a limiting switch seat 8, a limiting switch 9, a linkage 10, a limiting plectrum 10-1 and a plectrum.

Detailed Description

A360-degree rotation device of a holder is shown in fig. 1 and 2, and comprises a shell 1 and a driving motor 2, wherein a bearing disc 3 is arranged on the upper side of a bottom plate 1-1 of the shell 1, a gear ring 4 is sleeved on the bearing disc 3, the driving motor 2 is arranged on the lower side of the bottom plate 1-1, a pinion 5 is arranged at the output shaft end of the driving motor 2, and the pinion 5 is meshed with the gear ring 4; the bottom of the bearing disc 3 is fixedly connected with a linkage piece 9, the linkage piece 9 is positioned at the lower side of the bottom plate 1-1, a limiting plectrum 10 is arranged on the linkage piece 9, and a plectrum 10-1 is formed on the limiting plectrum 10;

a follow-up limiting ring 6 which is coaxial with the bearing disc 3 and can rotate is positioned at the lower side of the bottom plate 1-1, a limiting contact 6-1 and two limiting protrusions 6-2 which are spaced at a certain angle are formed on the follow-up limiting ring 6, the limiting contact 6-1 is positioned at the middle position of the two limiting protrusions 6-2, meanwhile, two limiting switches 8 are arranged at the lower side of the bottom plate 1-1 through a limiting switch seat 7, a certain spacing angle is formed between the two limiting switches 8, and the limiting switches 8 are electrically connected with a controller of the driving motor 2;

the limit contact 6-1 of the follow-up limit ring 6 can touch the limit switch 8 in the clockwise or anticlockwise rotation process, and the interval angle between the limit bulge 6-2 on the follow-up limit ring 6 and the limit contact 6-1 is not smaller than the interval angle between the two limit switches 8; the shifting head 10-1 of the spacing shifting piece 10 can shift the spacing bulge 6-2 on the follow-up spacing ring 6 in the clockwise or anticlockwise rotation process so as to enable the follow-up spacing ring 6 to rotate together.

As can be seen from fig. 2, if the follow-up limiting ring 6 is not provided, the limiting pulling piece 10 is limited by directly using the two limiting switches 8, and since the two limiting switches 8 have a certain volume, an angular interval is inevitably required in the arrangement, so that the actual rotatable angle of the limiting pulling piece 10 is less than 360 °, and 360 ° rotation of the bearing disc 3 cannot be realized.

After the follow-up limiting ring 6 is arranged, the two limiting switches 8 are used for limiting the rotation of the follow-up limiting ring 6, and the rotation limiting of the limiting pulling piece 10 is taken charge of by the two limiting protrusions 6-2 of the follow-up limiting ring 6;

when the bearing disc 3 rotates, the shifting head 10-1 of the limit shifting piece 10 rotating along with the bearing disc 3 pushes a certain limit protrusion 6-2 of the follow-up limit ring 6 so as to drive the follow-up limit ring 6 to rotate together, when the shifting head 10-1 of the limit shifting piece 10 faces the limit switch 8, because a certain angle interval exists between the limit protrusion 6-2 of the follow-up limit ring 6 and the limit contact 6-1, the limit contact 6-1 of the follow-up limit ring 6 does not reach the limit switch 8 at the moment, the limit shifting piece 10 still can rotate (namely, the bearing disc 3 still can rotate) until the limit contact 6-1 of the follow-up limit ring 6 contacts the limit switch 8; after the limit switch 8 is triggered, the driving motor 2 stops or reverses.

Thus, the presence of the follower limit ring 6 compensates (expands) the angle at which the limit dial 10 is rotatable (clockwise and counterclockwise). Because the spacing angle between the spacing bulge 6-2 and the spacing contact 6-1 on the follow-up spacing ring 6 is not smaller than the spacing angle between the two spacing switches 8, the clockwise and anticlockwise rotatable angle of the bearing disc 3 can reach and exceed 360 degrees.

The above embodiments are only for illustrating the present utility model, not for limiting the protection of the claims, and any insubstantial modifications made on the basis of the essential aspects of the present utility model should fall within the scope of the protection of the present utility model.
